Hello shmem,

Thanks for you reply.

i call redirect_elog the first thing in the program and i tried the other approach too ie  open(STDERR, ">>$file") or die, it still gives the same problem.

The code i have is something like this.

#!/usr/local/bin/perl -wT

use strict;
use TEST::App::MainApp;

$SIG{__WARN__} = \&warn_handler;


redirect_error_log("/export/home/rdave/logs/error_log");
my $app = TEST::App::MainApp()
$app->run_loop();

use constant MAX_MSGLEN => 1022;

sub warn_handler
{
    my $msg = join "", @_;
   # print to STDERR
    $msg = "[" . "$$|" . time2iso() . "] " . $msg;

    # send in chunks, if necessary
    while (length $msg > MAX_MSGLEN) {
        my $chunk = substr($msg, 0, MAX_MSGLEN);
        $msg = substr($msg, MAX_MSGLEN);
        warn $chunk, "\n";
    }
    warn $msg;
}

Then in the run_loop in another package

sub run_loop
{
    my ($self) = @_;

    my $requester = $self->requester;
    $self->{_REQUEST_NUMBER}=0;
    # initialize the request counter
    while (my $input = $requester->new_request()) {

        $self->_reset_timings;

        # start request timing
        begin_timing('REQUEST');

        $self->scratch->init;

        ++$self->{_REQUEST_NUMBER};
        warn "[--] Starting a new request $self->{_REQUEST_NUMBER} (Cl
+ient: $ENV{REMOTE_ADDR}) ...\n";

        $self->{_INPUT} = $input;

        # read application configuration
        $self->config_object->getConfig($self->name());

        # process request
        $self->_process_request;

        # finish the request
        $requester->close_request();

        $self->invoke_post_request_callbacks;

        # end request timing
        $self->timing('REQUEST', time_since('REQUEST'));

        
        warn "[--] Finished handling request $self->{_REQUEST_NUMBER} 
+...\n";

        $self->post_request;

}

I am not changing or redirecting STDERR anywhere else in the program other than the first time. In the above code snippet the first warn goes to /usr/local/apache/logs/error_log and the bottom one goes to local log file. The code is spread over 1000s of lines, so sorry could'nt post it, but one thing is sure, that the program is not touching STDERR/redirect_elog/LCSTDERR elsewhere and this one works fine with perl 5.6.1 and behaving this way with perl 5.8.5
